Abstract: A method is proposed to induce the sensation of movement in subjects in flight simulators and in cosmonauts, creating a cognitive simulation of movement through the Vestibular Electrical Stimulation. The system consists of a control unit, a function generator and a power amplifier. The device injects electric current over the mastoid process (galvanic vestibular stimulation), capable of activating the neurons of the vestibular system and inducing a movement sensation, in coordination with a flight simulation program or subject's movement in the simulator. The use of the device modifies eye movement control responses, electrically activating the vestibular-ocular, vestibulo-colic and vestibule-spinal reflexes. The main purpose of this device is to provide sensory input to enhance the experience in pilots during flight training or in microgravity.

Abstract: A vestibular prosthesis includes micro-electric-mechanical (MEMS) sensors, gyroscopes in each sensitivity axis (X, Y, Z), accelerometers in each sensitivity axis (X, Y, Z) to detect an angular and linear movement providing displacement measurements, gyroscopes in each one of the spatial axes (X, Y, Z), a microprocessor connected to the MEMS sensors and producing an electric pulse pattern or a continuous galvanic current pattern, a conditioning unit that amplifies and conditions the microprocessor output to apply current to the stimulation electrodes, the microcontroller being configured to determine the displacement of the cupula and the otolithic mass, determine a membrane potential as a result of a displacement detected by the MEMS sensors by means of determining a transduction current, and determine an action potential discharge pattern for the primary afferent neuron, which synapses with the hair cell by means of a mathematical model of the informative process of the vestibular mechanoreceptor.
